Namely, an electromagnetic valve 90 is turned on to start an operation of an air pressure assister 71 and an assist force is generated to lighten the shift lever 95. Thereby, a gear disconnection of a manual transmission 76 can be carried out. When a gear of the manual transmission 76 is engaged, a controller 72 starts a connection of a clutch 8. In this case, an electromagnetic valve 90 is maintained to be turned off in spite of connection/disconnection of the clutch 8 during neutral-studying and the assist force is not generated. Thereby, the gear engagement is prevented during studying and an unintensional starting, i.e., a driver's unintension is prevented.
